Embodiment Construction

[0019] figure 1 A schematic sectional view of an embodiment of an electric shaver 1 constructed according to the invention is shown. The shaving device 1 has a housing 2 formed such that a user can hold the shaving device 1 in his hand. Mounted on the housing 2 are two support arms 3 , on which the shaving head 4 is suspended by means of two journals 5 for a pivoting movement about a pivot axis 6 . The pivot axis 6 is formed in the region of that side of the shaving head 4 facing away from the housing 2 . The shaving device 1 also includes a linear oscillating motor 7 consisting of a stator 8 and a rotor 9 . The stator 8 is arranged in a housing 2 which also accommodates an electronic control unit 10 for controlling the linear motor 9 and necessary other not shown components such as batteries. The stator 8 consists of an iron core 11 and coils 12 , wherein the iron core preferably consists of soft magnetic steel sheets arranged in a stack and the coils can be divided into s...

Abstract

There is provided an electric shaving apparatus including a pivotal shaving head. More specifically, in one embodiment, there is provided an electric shaving apparatus including a housing, a shaving head pivotal relative to the housing and including at least one shaving system, and an electric drive mechanism for driving at least one component of the shaving system. The drive mechanism includes a stationary stator and at least one rotor movable relative to the stator, wherein the stator is disposed in the housing and the rotor in the shaving head.

Description

technical field [0001] The invention relates to an electronic shaving device comprising a pivotable shaving head. The invention also relates to an electronic drive for a shaving system of an electronic shaving device with a pivotable shaving head. Background technique [0002] An electronic shaver with a pivotable shaver head is known, for example, from DE 36 10 736 A1. A shaving apparatus is disclosed here with a housing serving as a handle and a shaving head system pivotable relative to the housing about a pivot axis, the shaving head system having an upper blade and a lower blade. The pivot axis is positioned such that the entire available shaving surface engages the skin during shaving and an inclination of the shaving surface away from the skin is avoided. The handle houses an electric motor that sets a drive rod protruding from the handle into an oscillating swing. [0003] From DE-PS 1 009 968 is known an electric shaving device with a rigid shaving head driven by ...
